I haven't snagged SoB because I'm not a big fan of adventures ... personally, I think that adventures should be kept in things like DH and e-products used to focus on detailing the system further, adding depth to campaign settings or allow for alternative campaign settings ... Something like a group book (ie: Eurostar) would make a good book, detailing their tactics, stats and equipment with maybe a short adventure in the back. I'd love to see superhero group PDFs with some info on the characters, allies and enemies, as well as equipment, vehicles and bases ... then maybe have a module in the back that focuses on the group along with some plot hooks. The old Villains and Vigilantes module "Crisis at Crusaders Citidel" comes to mind when I think of the adventure types Also, a book on specific gadgets ... like a Robot Handbook, listing several robots for any campaign and having some flavored ones for use in specific genre conventions
As far as price ... PDFs IMHO should be low cost, ranging from $7 - $15 at most. I know that I wouldn't pay for anything higher cost than that. Color pics would be nice, though not entirely nesscessary ... gimme crunchy bits and a nice format with some good illustrations of what's going on anyday
